Glade is a RAD tool to enable quick & easy development of user interfaces
for the Gtk+ toolkit and the GNOME desktop environment.
The user interfaces designed in Glade are stored in XML format,
enabling easy integration with external tools. In particular libglade can
load the XML files and create the interfaces at runtime.
Other tools are available which can turn the XML files into source code
in languages such as C++, Perl and Python.
